DOUBLE INVERTED TUBING FLARES
After preparing the tubing using the procedure in
PREPARING THE BRAKE TUBE FOR FLARING,
make a double inverted tubing flare using the follow-
ing procedure (Fig. 31).
CAUTION: When using brake tubing with Nygal
coating, always use flare nuts designed for this
coating. They have a larger hole in the center to
accommodate the coating on the tube.
(1) Install the replacement flare nut on the tube so
the threads are facing the flare yet to be made (Fig.
32).
(2) Open the Flaring Tool, Special Tool C-4047 (or
an equivalent), separating the tools vertical posts.
(3) Place the tubing in the jawed hole between the
two vertical posts.
(4) Slowly bring the vertical posts together captur-
ing the tube between the halves. Leave enough tub-
ing sticking through the top of the vertical posts to
allow for flaring. Apply only enough pressure to hold
the tube in place.

BRAKES TUBES AND HOSES
NOTE: Brake hoses for each brake are unique and
are not interchangeable.
Always use Mopartreplacement brake hoses to
ensure quality, correct length and superior fatigue
life. Care should be taken to make sure that the tube
and hose mating surfaces are clean and free from
nicks and burrs.
Use new copper seal washers on all connections
using banjo bolts and tighten all the fittings to their
specified torques.
Follow the procedures in the next three paragraphs
to reduce the potential for twisting the brake hose
during installation.
The flexible front hydraulic brake hose should
always be installed on the vehicle by first attaching
the banjo fitting to the disc brake caliper. Attach the
hose to the brake tubing before attaching it to the
front frame rail. Tighten all brake line fittings to the
specified torque.
On vehicles equipped with rear drum brakes,
loosely install the rear brake hose to the wheel cylin-
der first, then bolt the intermediate routing bracket
to the strut. Next, loosely install the hose to the steel
tube coming from the master cylinder. Attach the
hose bracket to the body. Finally, tighten the tube
nuts at each end of the brake hose.
On vehicles equipped with rear disc brakes, attach
the brake hose banjo fitting to the caliper first, then
loosely install the hose to the steel tube coming from
the master cylinder. Next, attach the brake hose
bracket to the body. Finally, tighten the tube nut at
the each of the end of the brake hose connecting to
the steel tube coming from the master cylinder.Only double wall 4.75 mm (3/16 in.) steel brake
line tubing with Nygal coating should be used for
replacement along with its special tube nuts. Care
must be taken when replacing brake tubing; to be
sure, use the proper bending and flaring tools, and
procedures to avoid kinking. Do not route the tubes
against sharp edges, moving components, or into hot
areas. All tubes should be properly attached with the
recommended retaining clips.
